Abstract

Structure de pare-chocs comprenant au moins deux éléments de flexion s'étendant transversalement entre deux zones de butée situées vers leurs extrémités. Les deux éléments de flexion 2, 3, sont réunis dans leur partie médiane 2m, 3m; le moment d'inertie d'un premier élément 2, suivant la direction longitudinale L, est minimal dans la partie médiane 2m pour augmenter de part et d'autre jusqu'à une valeur maximale pour une section S, puis diminuer jusqu'aux extrémités 2e; le second élément 3 présente, dans sa partie médiane 3m, la section à moment d'inertie maximale, le moment d'inertie des sections de ce second élément diminuant, de part et d'autre, jusqu'aux extrémités 3e. Applications aux pare-chocs de véhicules automobiles.Bumper structure comprising at least two flexing elements extending transversely between two stop zones located towards their ends. The two flexion elements 2, 3, are united in their middle part 2m, 3m; the moment of inertia of a first element 2, along the longitudinal direction L, is minimal in the middle part 2m to increase on either side up to a maximum value for a section S, then decrease to the ends 2nd; the second element 3 has, in its middle part 3m, the section at maximum moment of inertia, the moment of inertia of the sections of this second element decreasing, on either side, to the ends 3e. Applications to automotive vehicle bumpers.
